Tree scrolling problem

Hi to all,

I have a big tree and I need a way to scroll its content. That's why I have put the tree within a ScrollContainer. The problem comes when I expand the tree and try to select some of the bottom nodes (which have not been visible before scrolling to them). When I click such a node the vertical scroll bar is returned to its initial position, so that the node is again not visible. To click this node one more time I have to scroll to it again.

Is there any fix or workaround of this bug?

Thank you very much,

Antonio
